TIRE-BUILDING MACHINE (HORIZONTAL ADJUSTMENT).

Application filed December 26, 1918. Serial No. 268,401.

To all whom it may concern.

Be it known that I, WALTER H. Han-- MANN, a citizen of the United States of America, residing at Lancaster, in the county of Fairfield and States-of Ohio, have invented certain new and useful Improvements in Tire-Building Machines (Horizontal Adjustment), of which the following is a-specification, reference being had therein to the accompanying drawings;

s a continuation in part of the invention on tire building machines disclosed in my companion application filed undereven date, Serial No. 268,402, there is shown and described in this application a machine which is necessary when various sizes of tires are to be made or tires composed of various kinds of stock, so as to place within easy reach of a workman st'ock of various sizes and grades, without having a machine of tremendous size nor causing-a'workman to leave his station at the core or form on which the tire is fabricated. v

To this end, I have constructed a double or four unit machine, each unit or machine being similar to the machineabove referred to. and provided novelmea ns for horizon tally shifting each machine into active po sition convenient to a workman. Associated with theshifting'means are automatic stop devices, sothat after the shifting mechanism is placed in operation, it is automatically stopped upon one of the machines or units being correctly positioned.

This horizontal machine will be herein after described and then laimed, and refer ence will now be had to the drawings, wherein Figure 1 is a side elevation of the machine;

Fig. 2-is a front elevation of the base of the machine, partly broken'away and partly in section;

Fig. 3 is a plan of the machine, and

Fig. 4 is a horizontal sectional view taken on the line 1VIV of Fig. 1, also showing a line lllI on which Fig. 2 is taken.

In the drawings, the reference numeral 1 denotes an oblong box-like bed frame providing longitudinal parallel shears or ways 2 and for the guide flangeseland 5 respeetivelyof abase plate 6. The base plate 6 is slidable on the shears 2 and 3 and suitably mounted on the base plate are two tire building machines generallydesignated 7 and 8. These machines areidentical in construction and disposed side by side so that either machine may be conveniently used for supplying tire building material or stock of a desired size and grade. The machines 7 and 8 are bodily shiftable on the bed frame and one or the other machine is adapted to aline with a rotary core or form 9, preferably of the collapsiblerand knock-down type, supported by a chuck or other holding member 10 on a driven shaft 11. The shaft 11 is journaled in the upper portion of arhousing 12 mounted on an extension 13 of the bed frame 1, and in said housing or in proximity thereto is a motor 14, constituting a source of power for transmitting a rotary move ment to the core or form 9. This is accomplished through the medium of a train of gear wheels 15, shafting 16 and a two speed gear transmission mechanism controlled by levers 17 said transmission mechanism and the contents'of the housing 12 having been described in my companion application above referred to.

Journaled in the end walls of the bed frame 1 is a longitudinal shaft 18 having a screwthreadedv portion 19 in threaded en gagement with a depending nut 20, carried by the machine base 6 intermediate the ends thereof. That end of the shaft 18, adjacent the bed frame extension 13, is provided with loose beveled gear wheels 21 and 22 having clutch hub portions 23 adapted to be engaged by a clutch member 24 between the gear wheels 21 and 22 and slidably keyed on the shaft 18, so that said clutch member may be shifted into engagement with either of the clutch hubs 23 of the beveled gear wheels 21 and 22 to establish a driving relation between either of the beveled gear wheels and the shaft 18, and thus impart a desired rotation to the shaft 18 to shift the base 6 in a desired direction.

To impart movement to the beveled gear wheels 21 and 22 a beveled gear wheel 25 is employed, said gear wheel being mounted on the end of a shaft 26 journaled in bear lugs 27 carried by the bed frame 1, and the extension 13 thereof. The shaft 26 extends in proximity to the housing 12 and is pro vided with a beveled gear wheel 28 meshing with a beveled gear wheel 29 mounted on an angularly disposed shaft- 30 journaled in bearings 31 carried by the housing 12.

The inner end of the shaft 30 has a beveled gear wheel 32 meshing with a similargear Wheel on the shaft 16, and in consequence of this power transmission mechanism the motor 14; maybe employed for driving the shaft 16 and shifting the machines 7 and 8 rock shaft said rock shaft being journaled in the bed frame 1 and the extension 13 thereof.- That end of the rock shaft 35 within the extension 13 has a beveledgear wheel .36 meshing with a similar beveled gear wheel 37 on the lower end of a vertical rock shaft 38,'said shaft being journaled in suitable bearings provided therefor by the extension 13 and the housing 12. The upper end of the vertical rock shaft 38 has a crank or operating lever 39 in proximity to the other operating lever 17 of the housing 12, so that workman or attendant of the machine, stationed at'the core or form, may readily control the operation ofthe entire machine.

The guide flange 5 of the machine base 6 has a longitudinal groove 14: that maybe key shaped or dove-tailed in cross section. Slidable in this groove and adapted to'be fixed therein by set screws 15 or other securing means are stops 46 and 47 adapted to impinge against. an arm l8, carried by the rock shaft 35 and extending upwardly through a slot or opening provided therefor in the extension 13.

Assuming. that the machines 7 and 8 are capable of providing the necessary material or stock for building tire bodies on the core 9, it is only necessary for the operator ofthe machine toshift one of the operating levers 17 to place the core 9 at a desired'speed for the application of the material or stock from the machine 7 After a tire body has been built up from material or stock of the machine 7 and it is desired to build another tire body from the material or stock of the machine 8, or it is desired to use material or stock from both machines'in building a single tire body, then, the operator ofthe machine shifts the lever 39 and rocks the shafts 38, 35 and 40. Therocking of the shaft 35 moves the arm 48 out of engagement with the stop 17, and the rocking of the shaft 10 shifts the clutch member 24: into engagement with the clutch hub 23 of the beveled gear wheels 21 or 22 necessary to cause the longi tudinal shaft 18 to revolve in proper direction to feed the machines 7 to the right in order that its original position may be occu- The manner in which the shaft 35 is con-.

nected to the operating lever 39 and the clutch member 2% causes said lever and member to be restoredto a neutral posltlon, and

with the clutch member 24 out of engage ment with the clutch hubs 23 of bothof the beveled gear wheels 21 and 22, the machine 8 will remain in the position to which it-has been shifted so that the material orstock carried thereby may be applied tothe core 9 or to other stock. or material previously placed thereon; I U y In view of my companion application Serial No. 268,402 it is believed that the utility and advantage of using two machines, side by side, together with means for bodily shifting said machines will be readily understood, particularly by those'conversant with the art, and While in the drawings there is il lustrated a preferred embodiment of the shifting and controlling mechanism, it is to be understood that the structural elements are susceptible to such modifications'and-variations as fall within the scope of the ap-' pended claims.

What I claim is J 1. Means for supplying different kinds of material to a. driven tire building core comprising material carrying machines adapted to be shifted back and forth in a horizontalplane at a right angle to the vertical plane of the driven core so that the mate rial from either machine may be used on the core, power shifting means for said machines operatable in -synchronism with said core, and adjustable stops carried by said machines adapted to cause a 'cessation in the operation of said power shifting means when one of said machines is correctly posi- V tioned relative to the core.

2. Means for supplying different kinds of material to a tire building corefa's in claim 1, characterized by said shifting means including a clutch mechanism and rocking elements, automatically brought into action to place shifting means in operation.

The combinationof a bedframe, a housing on said bed frame, a core supported from said housing, machines slidable on said bed frame and adapted to be shifted in front of said core, and means in said housing and extending into said bed frame adapted to effect movement of said machines on said bed frame.

liThe same combination as set forth in claim 3, and wherein said means includes a screw and a nut in the bed frame, and a manually controlled clutch to determine the direction in whichthe machines are shifted.

5. The same combination set forth in claim 3, and wherein stop devices form part of said machines by causing a cessation in the shifting movement of said machines on said bed frame.

6. In a machine wherein various kinds of stock is adapted to be placed on a power driven core from machines movable relative to said core :-means supporting said machines to guide said machines in a straight line at an approximate right angle to the vertical plane of the core, machine moving means operatable in synchronism with said power driven core, and means against which said machines may impinge to control the operation of said machine moving means relative to said power driven core. a

7. A machine as called for in claim 6, wherein said machine moving means includes a screw shaft and a nut with a clutch mechanism controlling the operation of said screw shaft by said power driven core.

8. The combination of a core, core operat: ing means, stock supplying means for said core adapted to be shifted by said core operating means, a. rock shaft adapted to be manually actuated to control the shifting of said stock supplying means by said core operating means, and means on said rock shaft against which said stock supplying means may impinge to automatically con trol the shifting of said stock supplying means by said core operating means.

9. In a tire fabricating machine, the com bination of a core, supports for parallel pieces of stock, the support for one piece of stock being in alinement with said core and adapted to be bodily shifted sidewise away from said core as the other sup-port for the other piece of stock is bodily brought into alinement with said core, and means actuated by the receding support to control the advancing support.

10. A tire fabricating machine as called for in claim 9, and core operating means adapted to also bodily shift said supports for the pieces of stock.

In testimony whereof I afiix my signature in the presence of two witnesses.
